حلقات O-Ring من HNBR | AS568-152 | داش 152 | صلابة 90 (20 / عبوة)

I needed o-rings that could handle higher heat after my standard Buna-N ones kept failing on a hot water valve, and these HNBR ones are holding perfectly. The 90 durometer gives them a nice firm feel, and the package of twenty is plenty for a few spare sets.

These 90-durometer HNBR rings are noticeably stiffer than standard Buna-N, which is exactly what I needed for a high-torque pneumatic application. Tested them up to 275°F and they held pressure perfectly with no visible swelling.

I needed o-rings that could handle high heat without cracking, and these HNBR 90 durometer ones fit the bill perfectly for my hydraulic application. They seated nicely in the groove and have held up well under pressure so far.
